Abstract: A liquid crystal display system comprising a first display member overlying a second display member. Each member comprises two transparent layers (such as glass), coated with polariser and separated by a layer of liquid crystal. Each member has a set of individually actuable display elements. The display elements in the second member, and are visible through the first member.

Abstract: Box machine forming wheels are individually stabilized with a respective, frame mounted, stationary yoke disposed within the circumferential groove of a head wheel that is rigidly secured to the forming wheel. Lateral space between the yoke finger faces and the rotating groove walls is adjustably filled by rub plates mounted on dowel pins confined within yoke finger guide bores. A cone tipped adjustment screw cooperates with conical tips on the dowel pins to selectively expand the rub plate assembly for operational wear accommodation.

Abstract: In a product including at least a first layer of fibers, the layer residing in a thickened, shortened microundulated state as a result of longitudinal micro-compressive treatment, the layer is characterized by being shortened at least 20% of its original length in the direction of treatment, there being at least 10 microundulations per inch in the layer in the direction of the treatment, the compressed-together relationship achieved by the treatment being substantially preserved in said product with adjacent microundulations in said layer residing with their sides abutting one another. The microundulated layer is shape-retentive and has stored mechanical energy capable, under activating conditions, to cause the product to expand. Products, and a method of producing such products, are also described. The products include superabsorbent assemblages, tampons, pads, cushions and liquid distributing and storage articles.

Abstract: Device and method for preparation of a condom by a user. The device defines a circular surface adapted to receive the annular ring of a condom in retaining or sealing relationship and gas inflation source is provided for producing a gas flow into the condom. By producing a pressure level to cause a detectable loss of air if the membrane has porosity in excess of a predetermined maximum degree the user can effectively test the condom for leaks. By associating the gas inflation sources with a composition selected to reside in the condom during use and effective against sperm or disease organisms, the user may achieve an improved degree of protection.

Abstract: In a clothes washer of the type which has an array of tuckers and which is reciprocated vertically toward and away from the bottom of a container of washing liquid, a diaphragm is mounted to have an extended orientation during downward stroke for displacing liquid, and a relatively collapsed orientation during upward stroke, and a volume-outlining, clothes-restraining open uper structure provided over the diaphgram, this open structure extending upwardly from the diaphragm so that at least a part of it extends above the normal liquid level when the washer is in its lowest position. In action, as the diaphragm displaces liquid downwardly, the open structure, in following behind the diaphragm, restrains articles of clothes from moving inwardly over the diaphragm but allows liquid to move inwardly through the clothes and through the open structure to fill in behind the diaphragm.

Abstract: The exterior of a compressed tampon, e.g. for absorbing menstrual discharge, is formed from a bat of substantially aligned absorbent fibers that have been preshortened in a microundulated state as a result of longitudinal compressive pretreatment. The preshortening, generally more than 20% of original length of the fibers, is selected to permit substantial recovery of original dimension, there being at least 10 of the microundulations per inch prior to incorporation in the tampon. The microundulations are shape-retentive (in the dry state) and reside with the sides of adjacent microundulations close together. Because of the pretreated state, the absorbent fibers have stored mechanical energy in a predetermined selected direction within the final tampon. They are highly moisture sensitive, responsive to small amounts of liquid to cause release of the mechanical energy and expansion in the given direction to cause rapid expansion of the exterior of the tampon.

Abstract: There are disclosed methods and compositions for the controlled release of microbiocides by using a mixture consisting of (a) a hydrolyzable organic titanium compound or a partial hydrolyzate thereof, (b) optionally an organopolysiloxane containing hydroxyl groups or a carbinol-containing polymer, and (c) a microbiocide.

Abstract: This invention provides a quick and accurate gauging means for locating and clamping a guide onto the top surface and leading edge of a workpiece, with respect to the line of cut desired. During execution of the cut, the gauging member of the guide is automatically returned to its storage position and cocked for the next cut. This guide is completely operable with only one hand, leaving the other hand simultaneously free for holding and operating the portable hand power saw. This invention yields cuts that are accurate and more quickly executed than freehand cuts or cuts where other types of saw guides are employed.

Abstract: To prevent passengers in an elevator from opening the hoistway door when the car is well above the floor, a rotatable arm is located below the car and engages the hall door to prevent it from being opened. This arm may be reached from the floor, by opening the hoistway doors slightly, and rotated to disengage it from the door, which may then be fully opened.

Abstract: A jet propulsion efflux outlet assembly for effecting control of a flight vehicle in the pitch, yaw and roll senses having a nozzle through which efflux issues, a spoiler plate with an aperture through which the issueing efflux passes, the spoiler plate being movable laterally to effect control in pitch and yaw and being rotatable for control in roll.
